Georeferenced point clouds appearing like stripes

Post by nu__no »

Hi!

When I import a drone point cloud ungeoreferenced or already georeferenced with real coordinates (with Metashape), usually it works fine.
But when I join a TLS point cloud (ungeorreferenced) and try to georeference using "Picking points", ICP or even with “Translate/Rotate” command, the visualization changes a lot, showing points like stripes.
Also, generating DEMs, orthos or exporting in any format, the point cloud remains this bad look.

Why does this happen and how can I solve it?
I tried to look for and solve it in different ways, but I don't master the subject, and so I couldn't understand what to do.

It has been a systematic problem, and having the point clouds georeferenced in CC is very useful! (By the way, thanks for this awesome software!).

Thanks!

Sorry for the delay, I was travelling in the US.

I replied to your message on the LSF forum.
